In the normal condition" of the sonder' inf-,olianisnn the locking plat@ Q2 is' lield in ils sender mechanism returns to normal.

mechanism is moved from normal by turning of the handle 9, said locking plate is moved to its locking position by springs 27, and remains yieldingly held there until the ne end of these springs is attached to the locking plate and the other to the sides of the front cover or dialr plate 16, the locking plate being slidably mounted on the under surface of the dial plate by means of rivets and guide bolts. The Winding mechanism which is set and released by these two controlling movements of the handle will now be described. The actuating latch or pawl 1S on the crank lever 17 engages the notch 28 'on an arm 29 which thereby is forced to participate in the rotary movement of the handle until the pawl 18 releases it by being thrown out of alinement with the arm through the rocking movement of the crank lever 17 caused by the depression of the knob 10. This rocking movement is illustrated very clearly in Fig. 6. The arm 29 is attached to one end of a shaft 30, the other end of which is slit in the center to receive the inside end of a spiral spring 31 having its outer end secured to the side of a projecting casing or shell 32, which in turn is secured rigidly to a bracket 33 fastened to the bottom supporting plate 34.

The impulse sending mechanism consists of a series of spring contact members 35, 36, and 37. Spring 37 is adapted through the medium of an insulating knob 38 to break the connection between springs 35 and 36 which are connected to the wires of the substation circuit leading to the central oflice.

. A toothed wheel 39 is adapted in its rotation to operate spring 37 once for each tooth, that is, to break the connection between springs 35 and 36. This toothed wheel 39-is mounted on a sleeve 40 running loose on shaft 30 and moved by a ratchet Wheel 41 mounted on the other end thereof, said ratchet wheel being engaged by a pawl 42 attached to the arm 29. The toothed Wheel 39 may therefore be rotated a definite number of stops depending on the angular displacement of the arm 29. which depends entirely on how far from its normal position it has been moved by the handle and crank lever. A definite number of impulses may be sent over the line by breaking the connection between the springs 35 and 36 a corresponding number of times; and the parts are so proportioned that the number of impulses to be used in each case are indicate@ on the dial plate adjacent to the di'erent positions in which the handle may be placed. A governing mechanism for the regulation of the speed at which these impulses may be sent is provided, consisting of a gear wheel 43, afliXed to and participating in the movements of the sleeve 40, engaging a pinion 44 which is mounted integrally with a worm Wheel 45 on shaft 46. The worm wheel 45 enga ges the worm 47 of a governor 48 having weights 49 attached to the free ends of its springs 50. It will be evident that this governing mechanism retards the return movement of the impulse sending mechanism under tension of spring 31.

As hereinbefore mentioned. the handle 9 is locked in the operative position to which it may be advanced, being thereafter released When the mechanism is ready to be operated for the sending of the second series of impulses for the selection of another digit. This releasing of the handle is brought about by the stop 26 engaging the projection 51 on locking plate 22 and moving it into an unlocking position against the tension of the springs 27 and up against the stop bracket 52 fastened to the dialA plate. op 26 is for that purpose aflixed to the arm 29 and unlocks the handle at the end of the return movement of the arm, thereby making it impossible for the operator to manipulate the mechanism for the sending of a second series of impulses until an interval sufficient for the proper sending of the first series of im ulses has elapsed.

A brief summary o the operation is as follows: Thehandle 9 is rotated in a clockwise direction from the normal position shown in Fig. 2 and placed in front of the aperture 2O of the particular digit wanted, and then depressed so that the latch 21 thereon enters said aperture and a similar aperture 23 in the locking plate 22. The handle when thus depressed is locked by the locking plate 22 by reason of the slanting plane on the latch engaging the lip 24 on the plate and moving it to one side until the notch 25 in the latch 21 registers with the lip 24 when the plate slides back to normal position and locks the handle. When the handle is thus manipulated the actuating pawl 18 on the crank lever 17 engages the arm 29 which thereby is forced to participate in the rotary movement until released by the pawl 18 which is thrown out of alinement therewith by the rocking move# ment of the handle.

The rotation of the arm 29 winds a spring 31 through the medium of the shaft 30, and said arm Will therefore when released rotate the impulsesending wheel 39, by means-of the pawl 42 and ratchet Wheel 41 attached respectively to the arm and to the sleeve 40 carrying the impulse-sending wheel. The rotation of the Wheel 39 causes through the manipulation of the springs 35, 36 and 37 the sending of the selected number of impulses overv the line. The stop 26 will, when the arm 29 is near the end of its return journey to nor- Vmal, shift the locking plate suliiciently to It -is 'obviousf'that -niany -modicatioi`i`s,
